MT82 D4 Gear ratios

[Dave2013M3]

Really that good to know. What is your RPM doing 70 to 75 mph

What gear? I think right at 3k rpm at 75mph 6th gear

Just wanted to add, going with a set of 4.09 gears alleviates almost all the issues as far as gearing when it comes to the MT82D4. I have a set of 4.09s on my 2020 Mustang GT 6spd and it was a mod I wish I did when I first got the car and didn't wait 2 years to do it. The only gear which is still too tall after the 4.09 install is 4th. However, 1-3 is a huge improvement.

I put 4.10 gears in my 2011 and 2017 within the first 100miles of owning the car it’s litterally the best upgrade you can do in my option it gives the car a more aggressive response and driving feel throughout every gear , I wish ford gave the option would be a no brainer for me. My 2017 was Whipple with 4.10 and 900whp talk about a monster

Found another thread on this. Seems most of the kinks were worked out. D4 doesn't seem to have the broken fork issues so much (maybe only driver error now?) or high rev shift issues. Maybe rev matching will help some folks as well.

There’s absolutely nothing that will fix the high rpm shift issues except a clutch and pressure plate swap, ask me how I know lol

Ben Calamore at Calamore Transmission rebuilds MT 82 trans and makes them bad ass. He said he took the new D4 apart and it the exact same Transmission inside

AFAIK, Ford has said it's the same as well. But there are conflicting reviews among those who have driven both the new car mt82 and the Tremec, where they too acknowledge they've been told it's the same, but it feels different. Probably just a fluke.

Bumping an old thread here, but are any 4.09 options on the horizon for us?

Ford won't be offering the gears in their catalog but they do have calibrations coming out via the ProCal tool that will allow 4.09 gearing. However, other brands are available through StrangeEngineering and others. I asked Ford Performance why they aren't offering it, they said it didn't sell. To be frank, one of the best mods I ever did on my S550. If you look around there are some shops that still have the Ford Performance ones in stock.

I have a base M6 with the 3.55s and it is BEGGING for some gear
